Improvement in hose-rings



tnited' gitane GEORGE SEWELL, OF BROOKLYN, NEW YORK,

Letters Patent No. 111,981, dated February 21, 1871.

IMPROVEMENT lN HOSE-RINGS.

The Schedule referred to in these Letters Patent'an. making part oi the `same.

manner the coupling tohose, tubes, and the like,

without injury to the hose.

My invention consists of an inner open ring clasped and drawn together by an outer closed ring, so as to bind and clasp the end ot' the hose between the ontside of the shank ofthe coupling and the inside of the open ring. The Shanks ot' the coupling are usually formed with corrugations or grooves. The inside of the open ring is grooved in a similar manner, so that the grip on the end of the hose is made Very firm.

The following description will enable any one to make and use my invention.

In the drawing- Figure 1 is a sectional view and elevation, and

Figure 2 a plan view.

The same letters refer to like parts in both 'Iigures- The essential parts of the invention are two metallic rings, A and B, having inclined surfaces, upon which a thread or screw is cut so that one will fit into and over thc other, as shown in ng` l. The inner ring B has a piece taken out, as shown at c, gs. l and 2. Since 'the inner face ot' ring A is inclined to the outer face ,of ring when rino' A is screwed over ring l5 the diameter of B is contracted so as to close more or less the opening or slot c and bind ring 15 close around the cud of the hose.

The. outer ring A is provided wit-h lugs C, to receive a wrench or spanner, so as to apply power to screw up the ring A. Similar lugs may be placed on the lower side of ring B, so as to hold. it from turning untilV it is firmly grasped on the end of the coupling.

The following is-the mode of using my invention:

The open ring B is placed upon the end of the hose, and vring A placed-so that its screw-threads engage with the screw ong-J3. rllhe shank of the coupling is then inserted in the end ofthe hose. N ow, it will be evident that, by turning rinfT A so as to bring it over ring B, the diameter ot' the latter will 'be contracted "and it firmly grasped around the end ofv the hose.

To lmake the binding still firmer, the inside of ring B may be provided with bars d (l (l, as shown in iig. 1. By the use ot' this invention couplings of any of the ordinary forms may be readily attached to and detached from hose, so that, in case ot accident to either, it may be replaced.

The hose is not liable to be cut, as it is when a thimble is screwed directly uponit, and my invention is far more simple and efficient than the modes of' fastening the hose to the couplings now in use.

Having thusdeseribed my invention,

What I claim, and desire to secure by Letters Patent of the United States, is-

The closed screw-ring A, in combination with the open screw-ring B, arranged so as to attach hose to couplings, substantially as described.

I GEORGE SEWELL.
